10 Best External Backup Drive For Mac 2025 in the United States

The G-Technology 12TB G-DRIVE with Thunderbolt 3 and USB-C is a robust external backup drive for Mac users. With a substantial storage capacity of 12TB, it provides ample space for large files and extensive backups. The dual Thunderbolt 3 ports and single USB-C port with USB 3.1 support allow for high-speed data transfers, which is ideal for users who need to move large amounts of data quickly. The daisy-chaining capability is a robust feature, enabling the connection of up to 5 additional devices, which can be convenient for users with extensive setups. Its all-aluminum casing not only makes it durable but also adds a sleek, stylish look to your desktop setup.

The 7200 RPM rotational speed ensures efficient performance, making it suitable for both professional and personal use. The 5-year limited warranty from the manufacturer offers peace of mind regarding longevity and reliability. A notable drawback is its size and weight; measuring 8.27 x 5.12 x 1.79 inches and weighing 2.73 pounds, it is less portable and more suited for a stationary setup. Additionally, while marketed as portable, it may not be as convenient to carry around compared to smaller, lighter drives.

The lack of built-in backup software might be a downside for users looking for an integrated solution, though this can be mitigated by using third-party backup options. This drive is best suited for Mac users needing a high-capacity, reliable, and durable external drive for their desktop setup.

Additionally, it supports AES 256-bit hardware encryption, adding a layer of security for sensitive data. However, while the drive boasts excellent features, its price might be on the higher end compared to other external SSDs, and users who do not require such high-speed performance and large capacity might find it more than they need. It also requires a USB 3.2 Gen 2x2 port to achieve top speeds, which may not be available on all Macs. The included software, Magician, ensures firmware is up-to-date and offers extra encryption and drive health monitoring, adding value to the package. For Mac users seeking a robust, high-performance external backup drive, the SAMSUNG T9 Portable SSD 4TB stands out as a top contender.
